Product Category Filter hides sibling categories when selecting a category with

Hello,
I am using the WOODMART Product Category Filter widget in the shop sidebar with:
– Layout: List
– Filter structure: Hierarchical
– AJAX Shop: Enabled
I have a category structure similar to:
Irrigation
→ Irrigation Fittings
→ Compression
→ Connection
→ Drip Tape
→ Dripline Fittings
→ Drippers
→ Garden Fittings
The problem occurs when I select a category that has no child categories, for example Compression.
After selecting Compression, the Product Category Filter refreshes and the other sibling categories (Connection, Drip Tape, Drippers, Garden Fittings, etc.) disappear.
I would like the sidebar category filter to keep the parent category and its sibling categories visible, even when the currently selected category has no children.
For example, after selecting Compression, I would still like to see:
Irrigation Fittings
→ Compression (active)
→ Connection
→ Drip Tape
→ Dripline Fittings
→ Drippers
→ Garden Fittings
I noticed that WoodMart has the option “Show category neighbors if there is no children” under Theme Settings → Product archive → Page title, which provides similar behavior for the page-title category navigation.
Is there a way to enable the same behavior for the WOODMART Product Category Filter sidebar widget?
Ideally, I would like to achieve this using a native WoodMart setting or hook/filter rather than modifying theme core files.
Thank you.
